So compare this taken today (Feb 24) to my last photo (Feb 6), so, what is that, 18 days? A little over two weeks, not quite three weeks difference..
The light patches you can see in the photo are the areas that are still healing, perhaps scarring. The worn fins have pretty much healed and regrown.
Score one for the Praziquantel!
I haven't ruled out a second treatment at some point as I am still seeing, on occasion, little white dots on the fish that I can't identify. Sometimes they are not there anymore the next day, but sometimes they are, until maybe 2-3 days later. So I wonder if there are still flukes in the system and the occasional one is getting through the slime coat barriers but otherwise for the most part held at bay by the fishes' own immunities.
